The Arctic route is shorter (and cheaper in fuel and concommitant passenger fares) So why not from Vancouver "over the top" to Delhi, too?
WTF ! : pretty soon EMIRATES will be flying the northern route to Dubai, so where does this ETOPS ruling fit in, and how??
Baffling.

ETOPS is for twin-engine planes. Basically, because you have very little redundancy, you have to fly within a certain number of minutes from a habitable area.
747s and the A380s Emirates use have four engines. If you start having engine problem or an engine dies in the middle of nowhere, you can still fly the plane (with 75% thrust) for a longer time.
If you start having engine trouble on a twin-engine plane, you risk losing 50% of your thrust and the entire side of your plane.
That being said, as Malcolm mentioned the 777s can fly further than 180 minutes but it's not automatic and depends on the carrier.
While Air Canada has some 777s that fly long ranges, I'm not sure they would want to use one on an India route. For a few reasons, I'm guessing:
- They couldn't quickly change this route to a 767-sized plane to reflect seasonal demand changes
- They would have to drop the route suddenly if the 777 went in for maintenance or went out of commission
- ETOPS regulations may prevent them from doing so
I don't know if those are the actual reasons, but that's what comes to my mind. I'm sure there are technical challenges when flying over the pole and most of Air Canada's fleet is aging. I bet Air Canada would LOVE to have a direct route from Vancouver on a 767-sized plane. They're waiting for the 787... which will have the range and size to make it profitable.
